In addition to its other functions, Apple’s iPhone is an incredibly flexible recording device. Depending on the app you use, you can record voice notes, create DJ mixes or even multitrack musical instruments anywhere you can take your phone. If you want to connect a line-level source such as a mixer, however, you’ll need outboard gear that may be as simple as a cable adapter from RCA plugs to your iPhone’s headphone/mic jack or as powerful as a dedicated audio interface.
